Child Support Calculation Worksheet - Kentucky
Kentucky child support calculation worksheet
County: [____________] Case number: [____________] Calculation date: [____________]
Parent A: [____________] Parent B: [____________]
Children covered: [names and birth dates: ____________________________________]
Order type: ☐ Initial ☐ Modification Existing monthly amount, if any: $[____________]
Proposed obligor: ☐ Parent A ☐ Parent B. For equal shared parenting time, KRS 403.2122(3)(a) treats the parent with higher gross monthly income as the obligor. For split custody, prepare one calculation for each household and use the difference under KRS 403.212(8).
1. Monthly income and permitted adjustments
Record actual monthly amounts and attach current and past income documentation. For self-employment or rental income, determine gross income under KRS 403.212(3)(c), rather than copying taxable income. Exclude means-tested public assistance from gross income. Explain any income imputed under KRS 403.212(3)(e).
| Item | Parent A | Parent B |
|---|---|---|
| Wages, salary, overtime, commissions, bonuses | $[____] | $[____] |
| Net income from self-employment, rent, royalties, or business | $[____] | $[____] |
| Retirement, investments, benefits, maintenance received, and other countable income | $[____] | $[____] |
| Monthly gross income | $[____] | $[____] |
| Current maintenance for a prior spouse actually paid under an existing order; current maintenance ordered in this case | ($[____]) | ($[____]) |
| Current support for prior-born children actually paid under an existing order | ($[____]) | ($[____]) |
| Support actually provided for other prior-born children for whom this parent is legally responsible, including any permitted imputed obligation | ($[____]) | ($[____]) |
| Monthly adjusted gross income | $[____] | $[____] |
| Share of combined adjusted gross income | [____]% | [____]% |
Combined monthly adjusted gross income: $[____________]. Calculate each share by dividing that parent's adjusted income by the combined amount. Income imputation or adjustment explanation: [____________________________________].
2. Guideline amount
Use the child support table in KRS 403.212(9) and the number of children for whom the parents share joint legal responsibility. If combined income exceeds the table, the court uses its discretion under KRS 403.212(7).
| Calculation | Amount |
|---|---|
| Number of children used for table | [____] |
| Combined adjusted income used for table | $[____] |
| Basic monthly support obligation from table | $[____] |
| Parent A's proportionate share | $[____] |
| Parent B's proportionate share | $[____] |
| Proposed obligor's initial proportionate share | $[____] |
Self-support reserve check: If the obligor's adjusted monthly gross income is at or below the applicable threshold in KRS 403.212(5)(b), separately calculate the obligation using that parent's income alone. Threshold: $[____]; reserve calculation: $[____]. Use the lesser applicable amount under subsection (5)(c). The usual $60 monthly minimum in subsection (6) is subject to the KRS 403.2122(3) exception.
3. Additional costs and payments
KRS 403.211(6)-(10) allocates reasonable necessary child-care costs due to employment, job search, or education leading to employment; qualifying health coverage costs; and extraordinary uninsured medical expenses in proportion to adjusted income. Record who actually pays each cost so the order can account for direct payments.
| Expense | Monthly amount | Paid directly by | A share | B share |
|---|---|---|---|---|
| Qualifying child-care costs | $[____] | [____] | $[____] | $[____] |
| Child's health-care coverage cost | $[____] | [____] | $[____] | $[____] |
| Extraordinary uninsured medical expense allocation | $[____] | [____] | $[____] | $[____] |
Medical-expense note: Unless the parties agree otherwise, the parent maintaining the child's insurance covers the first $250 of medical expenses per calendar year; extraordinary uninsured expenses exceed that amount. Coverage and direct-payment notes: [____________________________________].
4. Shared parenting time credit, if applicable
KRS 403.2122 counts qualifying days, generally more than 12 consecutive hours in a 24-hour period, including substantially equivalent care as determined by the court. A parent needs at least 88 days per year of court-ordered time or time exercised by the parties' consent. The court applies the credit on the parent's motion and may make the adjustments described in subsection (3).
| Obligor's qualifying days per year | Adjustment percentage |
|---|---|
| 88–115 | 15% |
| 116–129 | 20.5% |
| 130–142 | 25% |
| 143–152 | 30.5% |
| 153–162 | 36% |
| 163–172 | 42% |
| 173–181 | 48.5% |
| 182–182.5 | 50% |
Obligor's qualifying days: [____]. Basis: ☐ Court order ☐ Parties' consent. Adjustment percentage: [____]%. Total support obligation on the prescribed worksheet: $[____]. Credit (percentage × that obligation): $[____]. Obligor's obligation after credit: $[____].
The self-support reserve and shared parenting credit are calculated separately; do not stack them. Enter the lesser applicable support amount under KRS 403.212(5)(c) and 403.2122(3)(c). The court retains the discretion described in KRS 403.2122(3)(b) and (6).
5. Proposed amount and court findings
| Item | Monthly amount |
|---|---|
| Obligor's applicable guideline amount after reserve or shared-time calculation | $[____] |
| Proposed adjustment for allocated costs, accounting for costs each parent pays directly | $[____] |
| Proposed monthly payment | $[____] |
Explain every cost adjustment and attach the current prescribed worksheet: [____________________________________].
Deviation requested? ☐ No ☐ Yes. KRS 403.211(2)-(4) permits deviation when applying the guidelines would be unjust or inappropriate, with the court's written or recorded reason. Ground and proposed amount: [____________________________________].
Modification, if applicable: Difference from existing monthly amount: $[____] or [____]%. Under KRS 403.213(1)-(2), modification requires a substantial and continuing material change; a change of at least 15% creates a rebuttable presumption in favor of materiality, and a smaller change creates a rebuttable presumption against it. Modified installments accrue only after the motion is filed. Facts supporting change: [____________________________________].
Duration note: Unless a written agreement or decree provides otherwise, KRS 403.213(3) ties termination to emancipation. If the child is still in high school at 18, support can continue while the child is a high school student, no later than completion of the school year in which the child turns 19. Record the controlling order's terms: [____________________________________].
Attachments: ☐ Income records ☐ Child-care records ☐ Insurance records ☐ Parenting-time order/agreement ☐ Current prescribed support worksheet.

Family law covers the paperwork that shapes divorce, custody, child support, adoption, guardianship, and other family matters. These filings are emotional and high-stakes, and they also have to meet strict procedural rules for service, financial disclosure, and parenting plans. Clean, accurate paperwork keeps the focus on getting a workable outcome for the family instead of getting derailed by technical problems that delay hearings or force amended filings.
